Feeding trials of green seaweed Ulva fasciata

For the nutritional evaluation of green seaweed Ulva fasciata, a feeding trial was performed in albino rats. The results indicated that the 20% replacement of seaweed U. fasciata instead of carrot or lettuce in rad diet causes no harmful effects, as evident by a non-significant change in blood constituents and serum enzyme levels. The weight gain observed in rats with U. fasciata diet was same as that of control diet. The true digestibility ratio of U. fasciata was 80.20% with carrot and 83.4% with lettuce. The data suggest that the green seaweed U. fasciata could be used as an alternative dietary component in animal fodder.
